A man believed to be America's oldest veteran is celebrating his 110th birthday on Wednesday.

Overton was born May 11, 1906, making him the oldest living World War II veteran after an 110-year-old Louisiana vet died last week. He fought in the 1887th Engineer Aviation Battalion in World War II, and served as a corporal in Hawaii, Guam and Iwo Jima.

His tips for longevity include chain-smokes cigars, a splash of whiskey in his morning coffee, and a steady diet of fried catfish and butter pecan ice cream, he told TODAY two years ago.
